Saltstack生产案例之Haproxy安装

cd /srv/salt/prod/

mkdir haproxy
mkdir keepalived
mkdir nginx
mkdir php
mkdir memcached
mkdir pkg

cd pkg

vim make.sls

make-pkg:
  pkg.installed:
    - pkgs:
      - gcc
      - gcc-c++
      - glibc
      - make
      - autoconf
      - openssl
      - openssl-devel
      - pcre
      - pcre-devel

先安装一遍haproxy取得配置文件等信息

cd /srv/salt/prod/haproxy/files/

把haproxy安装包拷贝到这个目录

cp /root/tools/haproxy-1.6.3.tar.gz /usr/local/src/

解压 haproxy

make TARGET=linux2628
make install TARGET=linux2628 PREFIX=/usr/local/haproxy-1.6.3

ln -s /usr/local/haproxy-1.6.3/ /usr/local/haproxy

由于不是默认安装 需要修改启动脚本

cd  /srv/salt/prod/haproxy/files/haproxy-1.6.3/examples

vim haproxy.init

拷贝

cp haproxy.init  /srv/salt/prod/haproxy/files

cd /srv/salt/prod/haproxy

vim install.sls

include:
  - pkg.make

haproxy-install:
  file.managed:
    - name: /usr/local/src/haproxy-1.6.3.tar.gz
    - source: salt://haproxy/files/haproxy-1.6.3.tar.gz
    - mode: 755
    - user: root
    - group: root
  cmd.run:
    - name: cd /usr/local/src && tar zxf haproxy-1.6.3.tar.gz && cd haproxy-1.6.3 && make TARGET=linux2628 PREFIX=/usr/local/haproxy && make install PREFIX=/usr/local/haproxy && ln -s /usr/local/haproxy-1.6.3 /usr/local/haproxy
    - require:
      - pkg: make-pkg
      - file: haproxy-install

可以执行安装试一下了

salt '10-8-86-172' state.sls haproxy.install saltenv=prod

PS：注意路径，默认使用base可以在后面加saltenv=prod使用prod

每次执行都会执行一次这个命令，这样不合理

继续学习状态间关系

1，unless 如果unless后面返回的值为真就不执行cmd.run   - unless: test -L /usr/local/haproxy

2，onlyif

再完善一下

include:
  - pkg.make

haproxy-install:
  file.managed:
    - name: /usr/local/src/haproxy-1.6.3.tar.gz
    - source: salt://haproxy/files/haproxy-1.6.3.tar.gz
    - mode: 755
    - user: root
    - group: root
  cmd.run:
    - name: cd /usr/local/src && tar zxf haproxy-1.6.3.tar.gz && cd haproxy-1.6.3 && make TARGET=linux2628 PREFIX=/usr/local/haproxy && make install PREFIX=/usr/local/haproxy && ln -s /usr/local/haproxy-1.6.3 /usr/local/haproxy
    - unless: test -L /usr/local/haproxy
    - require:
      - pkg: make-pkg
      - file: haproxy-install

/etc/init.d/haproxy:
  file.managed:
    - source: salt://haproxy/files/haproxy.init
    - mode: 755
    - user: root
    - group: root
    - require_in:
      - file: haproxy-install

net.ipv4.ip_nonlocal_bind:
  sysctl.present:
    - value: 1

/etc/haproxy:
  file.directory:
    - user: root
    - group: root
    - mode: 755
~                 

PS：net.ipv4.ip_nonlocal_bind:

      sysctl.present:

     - value: 1

是允许ip4监听

业务引用

把结构做一个调整新建两个目录一个cluster 一个modules

把之前建立的文件夹全部放入modules（所有的基础模块放在这里）业务放在cluster

刚刚的install.sls路径也需要修改

可以执行代表设置成功

salt '10-8-86-172' state.sls modules.haproxy.install saltenv=prod

业务引用

mkdir files
cd files/

cd /srv/salt/prod/cluster

vim haproxy-outside.sls

include:

haproxy-service:

    - enable: True
    - reload: True
    - require:
      - cmd: haproxy-install
    - watch:
      - file: haproxy-service

在top里面定义

vim /srv/salt/base/top.sls

base:
  '*':
    - init.init

prod:
  '*':
    - cluster.haproxy-outside

执行高级状态

salt '10-8-86-172' state.highstate
